RAILWAY-Roaman WORKING rroot..

application med December 29, 192i.l Sum No. 758,659.

lTo all whom t may concern.'

Be it' known that I, ConwILi. JA'CKsoN, a citizen of' the United States residing at tie of Illinois,

have invented certain new and useful Improvements in Railway-Roadbed VVOrking Tools, of which the following is a-"specification. t

This invention relates to improvements in railway road bed 'working tools,

The main-objects of-this invention are:

First, to provide an improved machine for loosening and .removing the ballast-from railway road beds. v

Second, to provide a machine of this character in which the ballast'between the ties is rapidly loosened'and removed to the side of the roadv bed.

j Third, to provide a machine of this character which is veryv simple in structure' and operation.

Objects pertaining to details and econo-v mies of construction and Operation of my improved machine will definitely appear from the detailed description to follow.

I accomplish the objects of my invention the devices and means described in the i illustrate the invention.

this application, in which of the tools thereon.'

following. specification. l The invention is clearly defined and pointed out inthe claims.

A structure embodying theJ features of my invention is clearly illustrated in the accompanying drawing forming apart of Fig. I is a fragmentary view partially in vertical section of a machine embodying the features of myJ invention, only such parts being illustrated as are deemed necessary to Fig.` II is a fragmentary side elevation. Fig'. III is a perspective View of a portion ofthe drop hammer or crosshead with one j In the drawing similar reference numerals indicate similar parts in all of the views.

Referring to the drawing,1 represents the ties of a railway track and -Qx'the rails thereof. t My machinein the embodiment illustrated comprises a frame 3 adapted as a truck body provided' with carrying wheels 4 adapted to travel upon a railway track. This frame has upright ways 5 in which the ingly mounted.

The means for lifting the crosshead comprises the Chains 7. The means for driving 'the chains is not'illustrated as this forms no crosshead or drop hammer Gis reciprocat part of thisinvention. A suitable driving means, however, is illustrated in my application for Letters Patent Serial No. 758,658 filed concurrently herewith. The crosshead is lifted by this actuating means and allowed to drop, acting as a drop hammer. The crosshead has recesses 8 on its under vside positioned to receive the rails of the track l"as indicated by dotted lines in Fig. I,

The crosshead has a plurality of tools 10 mounted'thereon in two sets ory groups, in the structure illustrated there being' three tools in each Yset and the tools of each set facing in opposite directions. These tools are pivoted at 11, the pivots being4 disposed longitudinally of the truck so that they are free to swing laterally, all the tools of a set swinging in the same direction.

The tools -have pointed tips 12 with shoulders 13 in spaced relation to the ends of the ti s. These tips are laterally directed,

the too sl being .forwardly curved so that when the tools come in contact with the vroadbed they tend to swing forwardly, striking the roadbed, and carrying the loosened material outwardly from the center of the road-bed. The movement of the tools is in-l dicatedby dotted lines in- Fig'. I.

It is the practice in railway engineering at certain periods to remove and Screen the ballast and replace it; also in realining or raising sections of the track itis necessary to remove more Or less of the ballast between the ties. -This may be quickly accomplished with my machine,l the ballastv being loosened and considerable portions of it moved to the sides ofthe road bed, very greatly lessening thefamountof hand labor required.

I have illustrated land ldescribed -my imfound very practical. yI have not attempted or` adaptations which I contemplate and I t provements in an embodiment' which I have have shown only such partsiof the machine as seem necessary to illustrate my improvements as' it is believed that the disclosure" made will enable those skilled in the art to embody or adapt my improvements as. may be desired. A y

Having thus described myinvention what I claim as new and desire to secure -by Letters Patent is:-

1. In a machine ofthe Class described, the combination of a truck ada tedlto travel` upon a rallway track, vertica ways on said truck, a crosshead constitiiting a dro hammer reciprocatinglyfmounted on sai wardly facing shoulders spaced from their tips. f f

2. In a machine of the class described, the combination of. a truck adapted to travel upon a railway track, vertical ways on said truck, a crosshead constituting a drop hammer reciprocatingly mounted on said ways and recessed on its under side to receive the rails of the track, means Ifor actuating said crosshead, and tools pivotally` mounted on said crosshead in opposed laterally facing sets, the tool pivots being disposedjlongitudinally ofthe truck, there being a plurality of tools in each set, said toolsl having laterally directed ends so that the tools tend t0 swing laterally upon contactingrwith the ballast of a track. w

3. In a machine of the class described, the combination of a truck adaptedl to travel .upon a railway track, vertical ways on said truck, a crosshead constituting a drop hammer reciprocatingly mounted on said ways, means for actuating said crosshead, and tools pivotally mounted on said crosshead to swing laterally of the track, said tools having laterally directed points so that the tools tend to swing laterally upon contacting with the ballast of-at'rack, said tools having forwardly facing shoulders .spaced from their tips.

4. In a machine of the class described, the

combination of a truck adapted to travel.

means for actuating said crosshead, and tools pivotally mounted on said crosshead to swing laterally ofthetrack, said tools having laterally directed ends so that the tools tend to swing laterally upon contacting with the ballast'of the track.

5. In a machine of the class described, the combination with a railway truck, of a crosshead reciprocatingly mounted thereon transversely of the track upon which the truck is traveling, and a plurality of tools pivotally mounted n said crosshead to swing laterally of the track on- Which the truck is traveling, said tools having laterally directed points and forwardly facing shoulders spaced from their tips.

6. In a machine of the class described, the combinatlon with a railway truck, of a crosshead reciprocatingly mounted thereon transversely of, the track upon which the truckis traveling, and a plurality of tools pivotally mounted on said crosshead to swing'laterally of the track on which the truck is traveling..
